Overview
iT3020 10 GHz Variable Gain Amplifier Description The iT3020 is a highly linear low noise differential variable gain amplifier with a bandwidth of DC to 10 GHz.
It is suitable for Automatic Gain Control (AGC) in high bandwidth applications such as a 10/12.
5 Gb/s STM-64/OC-192 receiver front end.
Offset correction and shutoff control are provided.
Both AC and DC coupling are allowed at the input and output.
High sensitivity allows the device to be used at the output of a transimpedance amplifier.
™ ™ ™ ™ ™ ™ ™ ™ ™ 3-dB bandwidth: 10 GHz Differential gain: 29 dB Bias supply: -5 V, 156 mA, and +5 V, 74 mA Power consumption: 1150 mW Gain control: 30 dB CMRR: Better than 25 dB DC offset correction Low RMS jitter Low-cost JEDEC QFP-N (MO-220) package Features www.
